DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively in conjunction with specific embodiments below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] Reference Figure 1 , Figure 2 This embodiment provides a battery pack 400 separation device, including a carrier plate 100, a propulsion mechanism 200 and a cutting mechanism 300, and may also include two limiting plates 500 and a limiting cylinder 600.

[0026] The carrier plate 100 is used to carry the battery pack 400 to be separated. Figure 3 , the carrier plate 100 is arranged horizontally and two linear grooves 110 are formed on the carrier plate 100, the two linear grooves 110 are arranged in parallel, the battery pack 400 is placed above the two linear grooves 110 and the length direction of a single battery in the battery pack 400 is perpendicular to the length direction of the linear grooves 110. Of course, in other embodiments, the linear grooves 110 can also be other numbers, such as 1, 3 or 4, and the number of the linear grooves 110 can be reasonably designed according to the length of a single battery in the battery pack 400 to be separated, and the length of the linear grooves 110 also needs to be reasonably designed according to the overall length of the battery pack 400.

[0027] The cutting mechanism 300 is used to cut the glue layer between the batteries in the battery pack 400. Figure 4In this embodiment, the cutting mechanism 300 includes a moving plate 310, a cutting drive, two reels 320, two limiting wheels 350, a cutting line 330 and two motors 340, and the cutting drive includes a mounting plate 360 ​​and a cutting moving module 370. The mounting plate 360 ​​is vertically fixed on one side of the carrier plate 100 and the mounting plate 360 ​​is kept perpendicular to the linear groove 110, and the cutting moving module 370 is fixed on the side of the mounting plate 360 ​​facing the carrier plate 100. The moving plate 310 is mounted on the slider of the cutting moving module 370 and is driven by the cutting moving module 370 to move up and down in the vertical direction, and the moving plate 310 is kept perpendicular to the linear groove 110. The two reels 320 are relatively rotatably mounted on the side of the moving plate 310 facing the carrier plate 100. The two motors 340 are both mounted on the moving plate 310 and the output ends of the two motors 340 are respectively connected to the cylinder shafts of the two reels 320. The two limiting wheels 350 are relatively rotatably mounted on the side of the moving plate 310 facing the supporting plate 100 and the two limiting wheels 350 are both located between the two reels 320, and the limiting wheels 350 are penetrated to provide limiting grooves. The two ends of the cutting line 330 respectively penetrate the limiting grooves of the two limiting wheels 350 and then are respectively wound on the two reels 320, and the cutting line 330 is always kept in a tensioned state, and the cutting line 330 is limited by the two limiting wheels 350 to prevent the cutting line 330 from running off. The two motors 340 drive the two reels 320 to roll respectively to adjust the cutting line 330, so that the cutting line 330 is kept in a tensioned state. In this embodiment, the cutting line 330 can be made of a metal wire with higher strength, such as a diamond wire. The two motors 340 drive the two reels 320 to rotate forward or reversely at a predetermined speed, so that one reel 320 unwinds the cutting line 330 and the other reel 320 rewinds the cutting line 330, so that the cutting line 330 moves in a circular motion.

[0028] The propulsion mechanism 200 is used to propel the battery pack 400 toward the cutting mechanism 300. In the present embodiment, the propulsion direction of the battery pack 400 is the length direction of the linear slot 110. In the present embodiment, the propulsion mechanism 200 includes two propulsion plates 210, a distance measuring sensor 250, and a propulsion driving member, and the propulsion driving member includes a bottom plate 220, a propulsion moving module 230, and a slide plate 240. The bottom plate 220 is located below the carrier plate 100 and the bottom plate 220 is connected to the carrier plate 100 through a bracket, the propulsion moving module 230 is fixed on the side of the bottom plate 220 facing the carrier plate 100, and the slide plate 240 is installed on the slider of the moving module and is driven by the propulsion moving module 230 to move horizontally in a direction perpendicular to the moving plate 310. The tops of the two push plates 210 respectively vertically penetrate the two linear grooves 110 and the two push plates 210 are both clearance-matched with the carrier plate 100. The bottoms of the two push plates 210 are fixed on the slide plate 240. In the initial state, the push plates 210 are located at one end of the linear groove 110 away from the moving plate 310. The distance sensor 250 is installed on the side of the moving plate 310 facing the carrier plate 100 and is used to detect the distance between the battery pack 400 and the moving plate 310. In this way, when the push moving module 230 drives the slide plate 240 to move along the length direction of the linear groove 110 close to the cutting mechanism 300, the slide plate 240 drives the two push plates 210 to move in the linear groove 110, and the two push plates 210 can push the battery pack 400 to move along the length direction of the linear groove 110. When the distance sensor 250 detects that the distance between the battery pack 400 and the moving plate 310 reaches a predetermined distance, it sends a signal, and the push moving module 230 stops working according to the signal of the distance sensor 250.

[0029] The limiting cylinder 600 is fixed on the carrier plate 100 and is located on one side of the battery pack 400. The two limiting plates 500 are arranged opposite to each other and the battery pack 400 is located between the two limiting plates 500. The limiting plate 500 close to the limiting cylinder 600 is connected to the piston rod of the limiting cylinder 600, and the limiting plate 500 away from the limiting cylinder 600 is fixed on the carrier plate 100. The limiting cylinder 600 is extended and retracted to drive the limiting plate 500 to move closer to or away from the battery pack 400.

[0030] Through the above structural arrangement, when the present embodiment is working, the battery pack 400 to be separated is first placed between the two limit plates 500, and the limit cylinder 600 drives the limit plate 500 connected thereto to move so that the limit plate 500 pushes the battery pack 400 to move closer to the other limit plate 500, and stops after moving a predetermined distance, so that the battery pack 400 is limited between the two limit plates 500; then the moving module 230 is pushed to drive the slide plate 240 to move, thereby driving the two push plates 210 to push the battery pack 400 to move in the direction of the moving plate 310, and when the distance measuring sensor 250 detects that the distance between the battery pack 400 and the moving plate 310 reaches the predetermined distance, a signal is sent, and the moving module is pushed. The group 230 stops working according to the signal of the distance measuring sensor 250; then, the cutting moving module 370 drives the moving plate 310 to move downward, and the two motors 340 respectively drive the two reels 320 to rotate alternately forward and reverse at a predetermined speed, so that the cutting line 330 moves back and forth in a cycle to cut the glue layer between the two adjacent batteries close to the side of the moving plate 310 to separate the two batteries; after the battery closest to the moving plate 310 is separated, the battery is unloaded, and then the cutting moving module 370 drives the moving plate 310 to move upward and reset, and the pushing moving module 230 continues to drive the slide plate 240 to move a predetermined distance, and the above operations are repeated to complete the separation of the entire battery group 400.
